NEW YORK CITY -- Donald Trump says he's leaving his "great business" so he can focus on being the nation's 45th president.

Trump tweeted early Wednesday that legal documents are being crafted to "take me completely out of business operations," adding, "the presidency is a far more important task!"

Trump had been under criticism for exposing himself to potential conflicts if he kept a role in his global business while being president.

He says he'll hold a news conference with his children on the subject on Dec. 15.

The tweets were as follows:

I will be holding a major news conference in New York City with my children on December 15 to discuss the fact that I will be leaving my ...

great business in total in order to fully focus on running the country in order to MAKE AMERICA GREAT AGAIN! While I am not mandated to

do this under the law, I feel it is visually important, as President, to in no way have a conflict of interest with my various businesses..

Hence, legal documents are being crafted which take me completely out of business operations. The Presidency is a far more important task!

Earlier Wednesday morning Trump also tweeted about the Ohio State attack: "ISIS is taking credit for the terrible stabbing attack at Ohio State University by a Somali refugee who should not have been in our country."
